Arvind Kandpal created FLINK-41480:
--------------------------------------
Summary: FailureEnricherUtils logs "[%s]" instead of the duplicate
output key
Key: FLINK-41480
URL: https://issues.apache.org/jira/browse/FLINK-41480
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Reporter: Arvind Kandpal
{{FailureEnricherUtils#filterInvalidEnrichers}} logs a warning when several
enrichers register the same output key:
{code:java}
LOG.warn("Following enrichers have registered duplicate output key [%s] and
will be ignored: {}.", <enricher class names>);
{code}
SLF4J only replaces {{{}}} placeholders, and the key is not passed as an
argument. The log prints {{[%s]}} literally, so users cannot see which output
key is duplicated.
*Fix:* use {{{}}} and pass {{entry.getKey()}} as the first argument.
